Lead Opinion
This is an appeal from the granting of a new trial in a medical malpractice action, which resulted in a substantial verdict for the patient’s personal representative. The plaintiff is Patricia Mead, executor of the estate of Lucille Humpal, deceased. The defendant is Dr. Burton Adrian.
The grant of a new trial was posited on two grounds: inconsistency in allowing the jury to award both wrongful-death damages and lost-chance damages, and failure to adequately instruct the jury as to the basis for determining lost-chance damages. After reviewing the record and considering the arguments presented, we affirm the judgment of the district court.
In April 1997 Lucille Humpal was seventy-three years old. During the first few weeks of that month, she began to feel weak and eventually became bedridden. By April 20 she was too weak to get out of bed, and an ambulance was summoned to her home. She was delivered to the emergency room of a Waterloo hospital. After a series of tests, she was released.
The results of a blood analysis revealed that Mrs. Humpal’s white blood cell count was 27,000. When that result was shared with her personal physician, Dr. Burton Adrian, he ordered that she be admitted to the hospital as an inpatient. She entered the hospital at 9:30 a.m. on April 21.
At the time of her hospital admission, Mrs. Humpal had a distended abdomen and was complaining of severe lower abdominal pain. Dr. Adrian saw her in the hospital that afternoon. His tentative diagnosis of her condition was an infection of the urinary tract. Because she had indicated to hospital personnel at the time of her admission that she could not recall having any recent bowel movements, Dr. Adrian ordered laxatives and enemas. X-rays taken at this time were inconclusive.
Over the next four days, Mrs. Humpal received five enemas, but they produced no relief from her abdominal pain. Her abdomen continued to be distended and by April 24 had attained the size of a basketball. On April 25 Dr. Adrian suspected diverticulitis. He ordered additional x-rays, which revealed that Mrs. Humpal’s colon had ruptured. Emergency surgery revealed an advanced infection of the area surrounding the ruptured colon. Mrs. Humpal died while the surgery was in progress. It was subsequently determined that she had been suffering from diverticulitis. Her cause of death was determined to be toxicity resulting from a spread of bacteria secondary to a ruptured diverticu-lum. Other facts that bear on the disposition of the appeal will be considered in our discussion of the legal issues presented.
I. The Issues Submitted to the Jury.
In her petition in this action, Mrs. Hum-pal’s personal representative claimed wrongful-death damages based on the alleged negligence of Dr. Adrian. The elements of damage requested in the petition included loss of accumulation to the decedent’s estate, interest on funeral and burial expenses, and physical and mental suffering.
At the conclusion of plaintiffs evidence, Dr. Adrian moved for a directed verdict. That motion was sustained with respect to the claim for loss of accumulation by the estate on the ground that there was insufficient evidence of such loss. The motion was overruled as to the other items of damage. The items of damage submitted for the jury’s consideration were:
interest on burial expenses
predeath physical and mental pain and suffering
predeath loss of full mind and body
lost chance of survival
As to all of these items of damage, the jury was instructed that to recover the personal representative must prove that the damages claimed were proximately caused by Dr. Adrian’s negligence and the amount of the damages. With respect to the claim for lost chance of survival, the jury was instructed:
Damages recoverable [for this item] are limited to the value of this loss of chance. This is measured by the difference between the chance of survival if treatment had been given at the earlier time, and the chance of survival at the time when treatment was given. Plaintiff may not recover for harm caused by the preexisting condition to which defendant’s negligence did not contribute.
The jury found that the following damages were proximately caused by Dr. Adrian’s negligence:
interest on burial expense $ 3,500
predeath physical and mental pain and suffering $100,000
predeath loss of ful mind and body $ 25,000 lost chance of survival $125,000
TOTAL $253,500
II. The Motion for New Trial.
Following the jury’s verdict, Dr. Adrian filed a motion for new trial in which he urged:
[The court submitted] both the traditional “all or nothing” damages and “lost chance of survival” damages to the jury. Both theories should not have been submitted to the jury. Submittal of both theories was not in accordance with Iowa law and resulted in improper, du-plicative and excessive damages being awarded by the jury under the court’s instructions. Plaintiff was fully compensated by the jury’s award of damages for the traditional elements for wrongful death allowed by Iowa law. Nevertheless, the court’s instructions allowed the jury to award an additional lump sum of $125,000 for the “lost chance of survival.” Since it cannot be determined whether the jury found for plaintiff on the “all or nothing” theory or the “lost chance of survival” theory, a new trial is required.
The district court granted a new trial for the reasons urged in Dr. Adrian’s motion and also for the reason that “the jury was not properly instructed on how to compute those [lost chance of survival] damages.” The grant of a new trial was conditional on Mrs. Humpal’s personal representative not agreeing to a remittitur of $125,000, the amount awarded for lost chance of surviv
The personal representative urges that both traditional death damages and lost-chance damages may be submitted to the jury. In addition, she contends that in the present case the recovery for lost-chance damages was not inconsistent with or du-plicative of the other damages awarded. To resolve this contention, we must consider the basis for recovering damages under a theory of lost chance of survival.
This court has considered allowing damages for lost chance of survival on three prior occasions. The case of DeBurkarte v. Louvar,
In Sanders v. Ghrist,
In Wendland v. Sparks,
As developed in our case law, the last-chance-of-survival doctrine is not an alteration of the traditional rules for determining proximate cause, but, rather, the creation of a newly recognized compensable event to which those traditional rules apply. It is manifest from the Sanders and Wendland decisions that a personal representative may recover damages for a lost chance of survival as an alternative to a traditional wrongful-death recovery. Recovery in such instances is for the lost chance of survival “evaluated independently.” Wendland,
In the application of these principles, it is important to identify the damages that are to be proportionately reduced to arrive at an award for lost chance of survival. Logically, this should be the amount of damages attributable to the death as such and should not include pre-death elements of recovery such as pain and suffering, loss of full mind and body, and increased medical expenses.
1. The present worth or value of the estate, which the decedent would reasonably be expected to have accumulated between the time of death and the end of the decedent’s natural life expectancy.
2. An award of interest on the reasonable funeral expenses of decedent for the length of time that they were prematurely incurred not to exceed the reasonable costs of a funeral for a person of decedent’s social and financial standing.
3.The value of services and support recoverable by a designated beneficiary under Iowa Code section 613.15.
Schmitt v. Jenkins Truck Lines, Inc.,
Predeath injuries, if proximately caused by the defendant’s negligence, are recoverable in full. They may be recovered in addition to the amount awarded for lost chance of survival. See David A. Fischer, Tort Recovery for Loss of a Chance, 36 Wake Forest L.Rev. 605, 620-21 (2001) (“The most accurate method of valuing damages [for lost chance of survival] is to award proportional compensation for damages, such as lost earnings, that should be reduced and to award full recovery for damages, such as extra medical expenses, that should not be reduced.”). Although such damages may be challenged based on insufficient proof, they are recoverable to the full extent that the evidence supports the jury’s award. In the present case, Mrs. Humpal’s preexisting condition may have made it difficult to separate the amount of the predeath damages that were caused by Dr. Adrian’s negligence from those that flowed from the preexisting condition. Nevertheless, there was evidence
The Sanders case is similar to the present case in that it involved alternative claims for traditional wrongful-death damages. Implicit in the reversal and remand that was ordered was a recognition that such claims may be asserted in the alternative. We are convinced that this should be allowed because a trier of fact might fail to find on the evidence that a negligent act was a proximate cause of a patient’s death yet believe that the negligence deprived the patient of a chance to survive. However, if both a traditional wrongful-death claim and a lost-chanee-of-survival claim are submitted, the proportionally reduced recovery for lost chance would be included within and duplicated by an award of traditional wrongful-death damages.
In the present case, the district court found that the proof of medical causation was sufficient to submit an ordinary wrongful-death claim to the jury. At the request of the personal representative, it also submitted a claim for lost chance of survival.
The only element of an ordinary wrongful-death recovery submitted to the jury was interest on burial expenses. Although the recovery allowed for that item was small when compared to the rest of the verdict, we believe it was nevertheless improper to allow an award for lost chance of survival when the jury found from the evidence that ordinary wrongful-death damages were proximately caused by the defendant’s negligence. The nature of a claim for lost chance of survival is such that it must be proportionally less than a recovery for traditional wrongful-death damages for the same decedent in the same case. Consequently, the trial court was correct in sustaining Dr. Adrian’s motion for a new trial.
III. The Remittitur Issue.
Dr. Adrian has attempted to appeal from that portion of the district court’s order conditioning the grant of a new trial on the refusal of the personal representative to accept a reduced award. There is no legal basis for pursuing such an appeal. Once the personal representative appealed the district court’s order for a new trial, the conditional feature of that order became of no force and effect. Iowa R. Civ. P. 1.1010(3). Notwithstanding rule 1.1010(3), this court is free to impose its own conditions for sustaining the district court’s grant of a new trial. Larsen v. United Fed. Sav. & Loan Ass’n, 300
The damages were itemized by the jury. The only element of damage challenged as improper in the motion for new trial was the award for lost chance of survival. The personal representative should be allowed to avoid a new trial by agreeing to delete that award in the sum of $125,000 from the total damages awarded. In the event that reduction is agreed to, interest on the remaining award shall be computed as provided in the original judgment. The election to accept the remittitur must be made within thirty days of the filing of the pro-cedendo in the district court.
We have considered all issues presented and conclude that the judgment of the district court should be affirmed. A conditional new trial is awarded and the case remanded to the district court for further proceedings consistent with this opinion.
AFFIRMED AND REMANDED.
Notes
. Dr. Adrian’s employer, Iowa Physician’s Clinic Medical Foundation d/b/a Integra Health, is also a defendant on a respondeat superior theory, but our opinion will proceed as if Dr. Adrian was the sole defendant.
. Claims were also included for medical expenses, but the personal representative made no attempt to have the court submit those claims to the jury.
. In Wendland v. Sparks,
. Some confusion on this issue has resulted from the statement in DeBurkarte that "the better approach is to allow recovery, but only for the lost chance of survival.” DeBurkarte,
. Dr. Adrian argued to the district court that in order to sustain a recovery for lost chance of survival there must be expert testimony concerning the probability of survival expressed as a percentage. We believe that when the claim is submitted as an alternative to ordinary wrongful-death damages it is unrealistic to require a claimant who is arguing that it is more probable than not that death resulted from the defendant’s negligence to also present evidence that the probability of survival was in fact some lesser percentage. The jury must determine the amount of proportionate reduction based on all of the evidence in the case.
Concurrence Opinion
(concurring specially).
I concur in the result reached in this case, but write separately to help the bench and bar better understand and utilize the loss of chance doctrine and to clarify some of the confusion I believe has arisen with its application in our courts. While we have adopted the loss of chance doctrine, we have yet to fully explain how it operates.
A complete understanding of the loss of chance doctrine begins with the venerable concept of causation. The perceived inadequacies and unfairness that resulted from the traditional application of this concept in some medical malpractice cases was the driving force behind our adoption of the loss of chance doctrine.
Seemingly from time immemorial, the concept of causation has served as the axis upon which legal responsibility turns in a negligence action. See W. Page Keeton et al., Prosser and Keeton on the Law of Torts §§ 41—45 (5th ed.1984) (collecting and discussing cases and other commentary on the development and application of causation analysis); see also John H. Wigmore, A General Analysis of Tort-Relations, 8 Harv. L.Rev. 377, 385-89 (189a-95). However, despite — or perhaps because of — the concept’s importance, its meaning and application have continuously vexed courts and commentators alike. See Gerst v. Marshall,
under any definition of causation, [the] element has two components: (1) the defendant’s conduct must have in fact caused the plaintiffs damages (generally a factual inquiry) and (2) the policy of the law must require the defendant to be legally responsible for the injury (generally a legal question).
Gerst,
Causation plays a vital role in a medical malpractice action just as it does in any other negligence action. In proving a case for medical malpractice, a plaintiff has the burden of “demonstrat[ing] the applicable standard of care, the violation of this standard of care, and a causal relationship between the violation and the harm allegedly suffered by the plaintiff.” Phillips v. Covenant Clinic,
In such cases, the application of the standards we have delineated to determine whether a defendant’s alleged negligence is the cause of the plaintiffs damages becomes problematic. In fact, some commentators have argued that the application of traditional causation principles to these cases is almost surely to arrive at an unjust result due to the increased difficulty of proving the necessary causal relationship between the action (or inaction) of the defendant and the harm to the plaintiff. See Joseph H. King, Jr., Causation, Valuation, and Chance in Personal Injury Torts Involving Preexisting Conditions and Future Consequences, 90 Yale L.J. 1353, 1363-64 (1981) [hereinafter King I], Under traditional causation principles, the threshold at which an entity is deemed responsible for a plaintiffs injuries is clear-cut: “[ujnless a causal connection is established under the applicable standard of proof (usually requiring that it appear more likely than not), the plaintiff will receive nothing for the loss in question.” Id. at 1356; see also Wendland,
The negativity surrounding the traditional causation approach arises partially from the observation that, in cases in which multiple factors come together to cause the plaintiffs injury, the all-or-nothing approach can make a plaintiffs recovery from a tortfeasor more difficult, if not impossible. This is particularly the case when a plaintiff suffers from a preexisting medical condition that is exacerbated by a negligent defendant, for example, a case in which a patient is already suffering from a potentially deadly affliction that proves fatal due, at least in part, to the defendant doctor’s delayed diagnosis and failure to begin treatment at an earlier point in time. In such a case, there are, essentially, two causes coinciding to bring about the ultimate harm to the plaintiff: a preexisting condition and the defendant’s negligence. Thus, even in a “close” case in which the plaintiffs ultimate harm results in equal parts from the preexisting condition and the defendant’s negligence, it is impossible to say the defendant more likely than not caused the harm. In such a situation, the traditional, all-or-nothing approach forecloses the recovery of damages even if the conduct of the defendant was truly negligent in some way. See id. at 1363-64.
Despite this precedent, the modern loss of chance doctrine did not arrive until the publication, in 1981, of Professor Joseph H. King’s groundbreaking study of causation and valuation in the torts context. See King I at 1353-97; see also King II at 502 (recognizing “[t]he traditional all-or-nothing rule went largely unchallenged in United States personal injury cases until about [1983],” shortly after the publication of Professor King’s original loss of chance article). But see also Hicks v. United States,
In DeBurkarte v. Louvar, we considered a number of causation issues surrounding a medical malpractice action arising from alleged negligence in the delayed diagnosis of breast cancer. See
We recognize that the plaintiffs injury may be viewed as a shortening of her life, in which case we would agree with the defendant that the plaintiffs did not produce substantial evidence on causation: there was no evidence the plaintiffs cancer probably spread after September 1981, preventing her from being cured.... On the other hand, as the Restatement [(Second) of Torts section 323] indicates, her injury may also be viewed as a lost chance to survive the cancer. The jury could then find from the evidence that the defendant’s failure to diagnose and treat the cancer probably caused a substantial reduction in the plaintiffs chance to survive it.
Id. (citation and footnote omitted). After making this observation, we went on to adopt the loss of chance doctrine arising out of the Restatement
Two years later, in Sanders v. Ghrist, we considered a challenge to jury instructions that the plaintiffs argued failed to properly encapsulate the loss of chance doctrine approved in DeBurkarte.
Our most recent reconsideration of the loss of chance doctrine came in Wendland v. Sparks, which involved a wrongful death medical malpractice action premised on the defendant’s failure to provide resuscitative care to a woman suffering cardiorespirato-ry arrest.
Ultimately, loss of chance is a discrete doctrine that has not yet fully developed within the broader context of tort law. Although there are examples of the doctrine’s application in other contexts, it has found its widest acceptance in the medical malpractice context in Iowa and elsewhere. See Wendland,
However, it is important to look back at the history and purpose of the loss of chance doctrine because both help frame an understanding of how it should operate at trial. As is underscored by the arguments advanced by the Estate and Dr. Adrian in this case, significant confusion has arisen around the actual meaning and application of the doctrine in Iowa. This is due in part to its complexity, but also is due to the fact that the doctrine has been the subject of much debate but comparably little resolution. Yet, the history and purpose of the loss of chance doctrine, as well as our prior cases, reveal three key points that guide its application.
First, loss of chance is a separate theory of recovery from a traditional negligence claim that is normally brought as an alternative claim in a traditional negligence action. When the claims are brought together in the same action, the jury must first consider the negligence claim, and in doing so decide whether the defendant’s conduct was negligent and caused the injuries alleged. If the plaintiff establishes the negligence claim, the jury does not further consider the loss of chance claim because even if the plaintiff may have also been deprived of a chance to avoid the harm, the negligence claim allows the plaintiff to recover all damages recognized to be compensable and established by the evidence. The loss of chance doctrine was created only to allow recovery when traditional negligence principles, particularly causation, preclude recovery by a plaintiff despite the existence of negligence by the defendant. Thus, loss of chance damages are only recognized within a loss of chance claim. Consequently, in considering a loss of chance claim, the jury must decide whether the defendant’s negligent conduct caused the plaintiff to lose a chance to avoid the ultimate harm. This means it is important in applying the loss of chance doctrine to focus on the defendant’s conduct apart from the preexisting condition even though the preexisting condition remains relevant to the contours of the doctrine when it comes to calculating damages. The plaintiff must establish the defendant’s negligence was a proximate cause of the lost chance to avoid the ultimate harm, and the instructions to the jury should be set up to reflect this approach. A loss of chance claim includes the basic elements of a traditional negligence claim — duty, breach of duty, causation, and damages.
Second, the injury for which recovery is sought under a loss of chance claim is not the traditional damages associated with a negligence claim, but is the lost chance of avoiding the ultimate harm sustained. See Alberts v. Schultz,
As revealed in this case and other cases, the two most confusing elements of a loss of chance claim can be causation and damages. The first two elements of duty and breach of duty are more straightforward and play out just as they would in an ordinary negligence claim. See id. at 1284 (“The basic test for establishing loss of chance is no different from the elements required in other medical malpractice actions.”). The plaintiff still must establish the defendant was negligent in his or her treatment or care of the plaintiff. Causation and damages, on the other hand, require a different approach. Not surprisingly, much has been written about these two issues, with commentators offering many theories as to how they interplay for a fact finder’s determinations when loss of chance is at issue. See King I at 1394-96; Aagaard, 96 Mich. L.Rev. at 1340-44.
A loss of chance claim is tied to an ordinary claim for negligence from a factual standpoint because both claims normally originate when a patient seeks medical attention due to some medical illness, injury, or malady. They separate, however, based on the impact of the preexisting medical condition that gave rise to the need for treatment on the ultimate harm sustained by the plaintiff. Under a claim grounded in ordinary medical malpractice, recovery is for the ultimate harm or injury, together with all other damages leading to the ultimate harm, caused by the defendant’s negligence. Yet, this claim cannot be established when the extent and nature of the preexisting medical condition precludes proof to a reasonable degree of medical certainty that the medical negligence was the proximate cause of the ultimate harm. See Alberts,
Damages under a loss of chance theory do not compensate the entire injury, but instead provide compensation for the reduced chance of avoiding the ultimate injury. Id. at 1284-85. This chance to avoid the ultimate harm is the item of value for which a plaintiff may seek compensation under a loss of chance claim. Id. Yet, the value of the loss of chance is best demonstrated in light of the actual harm sus
There have been numerous theories advanced for calculating the proper valuation of loss of chance damages. See, e.g., King I at 1381-87; Fischer, 36 Wake Forest L.Rev. at 619-21; Saroyan, 33 Cumb. L. Rev at 34-39; Aagaard, 96 Mich. L.Rev. at 1347-60. Yet, a consideration of the bevy of alternatives reveals that the theory of proportional valuation provides the most accurate method of valuation possible.
The proportional valuation theory allows for a full consideration of a preexisting condition and the defendant’s negligence, which is in line with our approach acknowledging that both are key to the alternative theories of recovery in loss of chance cases. This, in turn, promotes a cohesive factual presentation by the parties and a logical apportionment of damages by the fact finder. Proportional valuation requires the fact finder to determine the total value of the ultimate harm to the plaintiff under traditional damages theories while also ascribing a percentage value to the lost chance caused by the defendant’s negligence. See id. at 1382. From a practical standpoint, it is best for a court to instruct a jury to ascribe the percentage value to the lost chance. This value is the difference between the plaintiffs prenegli-gence chance of avoiding the ultimate harm and the plaintiffs postnegligence chance of avoiding the ultimate harm. See Cahoon v. Cummings,
Although the majority acknowledges that loss of chance damages should be calculated on a proportional valuation theory, it incorrectly concludes that the only items of damages used to calculate the total damages subject to a proportional reduction are those damages attributable to death, not pre-death damages such as pain and suffering and loss of function. This conclusion strikes a blow to the symmetry that has been developed within the doctrine, and conflicts with the approach we have been developing in our prior cases and that has been followed in most other jurisdictions.
The majority believes pain and suffering and loss of function damages are separately and fully recoverable in a loss of chance claim. Such an approach, however, essentially splits a loss of chance claim into two damage components consisting of damages for the lost chance to avoid the specific ultimate harm and all other damages short of the ultimate harm. It then values the ultimate harm proportionally in light of the lost chance, but awards the full value of the other damages. This position ultimately permits pain and suffering and other nondeath damages to be awarded without the necessity of establishing any causation. The majority fails to consider that the causation element of a loss of chance claim only requires the plaintiff to prove that defendant’s negligence caused a lost chance to avoid the ultimate harm. Additionally, the majority fails to consider how its approach would apply to a nondeath case, such as a case where the ultimate harm was an amputated limb. Under the majority’s position, only the ultimate harm — the amputated limb — would be proportionally valued. This means the plaintiff, under the majority’s approach, would be awarded a propor
Moreover, the history and purpose of the loss of chance doctrine reveals that it only becomes a viable theory of recovery once it has been determined that the very damages that the majority wants to separately award as a part of a loss of chance claim are not recoverable under the causation principles applicable to a negligence case. Thus, the majority wants to award damages that are precluded by traditional legal principles. Our adoption of loss of chance as a legal theory did not otherwise alter our venerable principles of causation. The majority’s position fails to consider that the sole recoverable damage in a loss of chance claim is the lost chance itself, and the means used to calculate this damage is to total all damages and award the percentage of the damages equal to the chance the plaintiff lost to avoid the ultimate harm because of the defendant’s negligence.
Considering the role and purpose of the loss of chance theory in a medical malpractice case, it would be incongruous for our law to permit full recovery of some items of damages under a loss of chance theory that could not be recoverable under a traditional negligence theory. The approach adopted by the majority elevates the mere chance to avoid a loss to the same level as the loss itself. Such an approach is totally inconsistent with traditional theories of causation, the loss of chance doctrine, and the body of law that has been developed since we first adopted the doctrine. The proper method of calculating damages is therefore to determine the total value of the plaintiffs injury arising from all the damages sustained, reduced according to the percentage of lost chance. Pain and suffering and loss of function are included in the total damages subject to the reduction. See Smith v. Washington,
In sum, the district court was correct to grant a new trial. A new trial is warranted because the loss of chance claim was not submitted as an alternative theory of recovery to the negligence claim, but was submitted as a blended claim that permitted the jury to award those damages ordinarily recoverable under a negligence claim in addition to the loss of chance damages. This was error, which the trial court properly recognized, warranting the grant of a new trial. While the majority also acknowledges the error, it has done damage to the development of the loss of chance doctrine in its effort to correct this error.
. We have traditionally described this doctrine as involving a "lost chance” or the "loss of chance.” Wendland,
. The Restatement (Second) of Torts section 323 (1965) provides:
One who undertakes, gratuitously or for consideration, to render services to another which he should recognize as necessary for the protection of the other’s person or things, is subject to liability to the other for physical harm resulting from his failure to exercise reasonable care to perform his undertaking, if
(a) his failure to exercise such care increases the risk of such harm, or
(b) the harm is suffered because of the other's reliance upon the undertaking.
We have applied or cited section 323 "with approval on a number of occasions,” including instances that did not involve the loss of chance doctrine described in DeBurkarte, Sanders, and Wendland. Estate of Long v. Broadlawns Med. Ctr.,
. Some jurisdictions permit an award of the plaintiff's full damages under the loss of chance doctrine. Zaven T. Saroyan, The Current Injustice of the Loss of Chance Doctrine: An Argument for a New Approach to Damages, 33 Cumb. L.Rev. 15, 35 n. 181 (2002-03) (collecting cases). Yet, such an award would effectively make defendants liable for both their own negligence and the patient’s preexisting condition, even though the condition was not caused by the defendant's negligent act or inaction. Cahoon v. Cummings,
. The trial court should complete the second portion of this equation in cases in which a jury serves as the fact finder. For this reason, the court must instruct the jury that its evaluation of the damages arising from the ultimate harm to the plaintiff should not include an estimation of the monetary value of the lost chance. Instead, the jury’s role is to evaluate the total value of the ultimate harm and designate the percentage of lost chance to avoid that harm. This approach will aid the jury in maintaining the proper separation between the all-or-nothing and lost chance theories, and permit appropriate oversight by the trial court to ensure that the proper amount of damages is awarded.
. Some commentators have made strong arguments that the proportional valuation method should not be applied to damages that arise from the lost chance itself and that such damages should be awarded in full. See David A. Fischer, Tort Recovery for Loss of a Chance, 36 Wake Forest L.Rev. 605, 620-21 (2001); Aagaard, 96 Mich. L.Rev. at 1344-47. In the words of one commentator, "The most accurate method of valuing damages [for loss of chance] is to award proportional compensation for damages, such as lost earnings, that should be reduced and to award full recovery for damages, such as extra medical expenses, that should not be reduced.” Fischer, 36 Wake Forest L.Rev. at 620-21. Under this theory, if a defendant doctor negligently misdiagnoses an infection that worsens, hastening a death, the plaintiff should be able to fully recover ancillary damage amounts such as the cost of additional doses of antibiotics that would have been unnecessary if a proper diagnosis had been made, and those amounts should not be subject to reduction because they are more closely related to the doctor’s negligence rather than the preexisting condition. See id. This case does not present the occasion to fully consider and decide this issue.
